Tomatis - neurosensory stimulation

I have recently had an Occupational Therapy assessment done with my 14yr old to see if it can help us identify what can help her in school. There was a lot of useful information but the general theme is that we need to learn how to regulate before we can implement more practical things.

they recommended a treatment called Tomatis which provides neurosensory stimulation to improve brain function, through bone stimulation with music on headphones.  It’s a long treatment and fairly costly - just wondering if anyone has any experience of this or if I’m being convinced to shell out money!

thanks in advance
